Geld
In short
Geld is the medium used to trade goods and services in an economy. It acts as a way to store value and measure how much things cost.
In plain words
It is what you use to pay for things like food or clothes. Instead of swapping a cow for a bag of wheat, you use money to make buying and selling much easier.
A simple example
If you go to a shop to buy a loaf of bread, you hand over a few coins or tap a card. The shopkeeper accepts this instead of asking for a piece of fruit in return.
Why it matters
Without it, people could only trade things they had directly with others. It allows businesses to grow and helps people save for the future.
Easy to mix up
It is often confused with wealth, which is the total value of everything you own, rather than just the cash used to buy things.
